This bill establishes a new Climate Coordinating Council within the Department of Homeland Security to coordinate efforts across the agency to identify, address, and reduce the impacts of climate change on its programs, operations, and personnel. The council would include at least 20 senior officials from various DHS components, including the Coast Guard, Customs and Border Protection, FEMA, TSA, and Immigration and Customs Enforcement, with leadership designated by the Secretary of Homeland Security. The council's responsibilities include identifying climate-related risks to DHS operations, developing climate change strategies and frameworks, recommending organizational changes to address those risks, and overseeing implementation of climate-related executive orders. The legislation requires the DHS Secretary to submit annual reports to Congress detailing the council's actions, beginning by January 1, 2025, and continuing for ten years. No new funding is explicitly appropriated in the bill, and the council would operate within existing DHS resources and authorities.
